C# Specflow上下文注入

下面是关于specflow中上下文注入的问题。我与我的实体有类：

public class OrderInfo
{
    public string Status { get; set; }
    public string OrderName { get; set; }
}

在另一个类中，我使用此实体创建新订单：

[Binding]
public class OrderSteps
{
    private NgWebDriver driver;
    private OrderInfo orderInfo = new OrderInfo();

    public OrderSteps(NgWebDriver driver,OrderInfo orderInfo)
    {
        this.orderInfo = orderInfo;
        this.driver = driver;
    }

    [When(@"I am creating new order")]
    public void WhenIAmCreatingNewOrder(Table table)
    {
        var orderListPage = new OrdersListPage(driver);
        orderInfo = orderListPage.CreateNewOrder(table.CreateInstance<OrderInfo>());
    }
}

---

所以问题是：如何使用第二个类中的数据，从填充了第一个类的数据的对象来看，似乎我找到了一个解决方案。我为我的OrderInfo创建了一个子类：

public class OrderInfoContext
{
    public OrderInfo OrderInfo { get; set; }
}

我的绑定类中有一些更改：

public class OrderSteps
{
    private NgWebDriver driver;
    private List<FilterInfo> filterData = new List<FilterInfo>();
    private OrderInfoContext orderInfoContext;
    private OrderInfo orderInfo;

    public OrderSteps(NgWebDriver driver, OrderInfoContext orderInfoContext)
    {
        this.driver = driver;
        this.orderInfoContext = orderInfoContext;
    }

    [When(@"I am creating new order")]
    public void WhenIAmCreatingNewOrder(Table table)
    {
        var orderListPage = new OrdersListPage(driver);
        orderInfo = orderListPage.CreateNewOrder(table.CreateInstance<OrderInfo>());
        orderInfoContext.OrderInfo = orderInfo;
    }
}

---

我认为原因是，如果您想在类之间共享数据，您必须初始化此数据一次，并且永远不要尝试再次编辑它，因为在您阅读它之前，它可以在途中的任何位置进行更改……这只是我的假设。您可以使用

ScenarioContext

并传递它。这种方法的优点是不需要向对象容器注册任何新内容

要在OrderSteps中创建“当前订单”，请执行以下操作：

[Binding]
public class OrderSteps
{
    private readonly NgWebDriver driver;
    private readonly ScenarioContext scenario;

    private OrderInfo CurrentOrder
    {
        get => (OrderInfo)scenario["OrderInfo"];
        set => scenario["OrderInfo"] = value;
    }

    public OrderSteps(NgWebDriver driver, ScenarioContext scenario)
    {
        this.driver = driver;
        this.scenario = scenario;
    }

    [When(@"I am creating new order")]
    public void WhenIAmCreatingNewOrder(Table table)
    {
        var orderListPage = new OrdersListPage(driver);

        CurrentOrder = orderListPage.CreateNewOrder(table.CreateInstance<OrderInfo>());;
    }
}

我还在ScenarioContext上创建了扩展方法，这也很方便：

namespace YourProject.Tests
{
    public static class OrderScenarioContextExtensions
    {
        public static OrderInfo GetCurrentOrder(this ScenarioContext scenario)
        {
            return (OrderInfo)scenario["OrderInfo"];
        }

        public static void SetCurrentOrder(this ScenarioContext scenario, OrderInfo currentOrder)
        {
            scenario["OrderInfo"] = currentOrder;
        }
    }
}

然后，只要有

ScenarioContext

对象，就可以调用这些扩展方法：

var order = scenario.GetCurrentOrder();

var order = new OrderInfo();

scenario.SetCurrentOrder(order);

更多信息：

[Binding]
public class BuyerPortalSteps
{
    private readonly NgWebDriver driver;
    private readonly ScenarioContext scenario;
    private OrderInfo CurrentOrder => (OrderInfo)scenario["OrderInfo"];

    public BuyerPortalSteps(NgWebDriver driver, ScenarioContext scenario)
    {
        this.driver = driver;
        this.scenario = scenario;
    }

    [Then(@"I am looking for order on buyer statistics grid")]
    public void ThenIAmLookingForOrderOnBuyerStatisticsGrid()
    {
        var buyerPortalDashboard = new BuyerPortalDashboard(driver);

        buyerPortalDashboard.CheckBuyerDashboardStatistic(CurrentOrder);
    }
}

namespace YourProject.Tests
{
    public static class OrderScenarioContextExtensions
    {
        public static OrderInfo GetCurrentOrder(this ScenarioContext scenario)
        {
            return (OrderInfo)scenario["OrderInfo"];
        }

        public static void SetCurrentOrder(this ScenarioContext scenario, OrderInfo currentOrder)
        {
            scenario["OrderInfo"] = currentOrder;
        }
    }
}

var order = scenario.GetCurrentOrder();

var order = new OrderInfo();

scenario.SetCurrentOrder(order);
